The state of the art of multicarrier modulation for the transmission of high-speed data With DSL technology poised to provide the fastest means of Internet access for years to come, there is a growing need for practical information on running xDSL services over existing telephone lines. Communications expert John Bingham draws on three decades of intimate involvement with data transmission research to provide a complete guide to the state of the art and future direction of multicarrier modulation (MCM)-one of the key methods for high-speed data transmission today. Geared to designers and system planners working with DSL modems, Internet access, and telephony, ADSL, VDSL, and Multicarrier Modulation presents everything engineers and programmers need to design MCM modems, understand current implementations, and formulate strategies for future improvements and research. Detailed, thoroughly logical coverage includes:<br> * Precise descriptions of problems associated with the transmission of high-speed data and how to solve them<br> * Clear explanations of the DSL medium and how to calculate its capacity<br> * Discussions of the theory as well as advantages and disadvantages of MCM<br> * A link between physical and higher layers for Internet access<br> * Essential yet hard-to-find information on spectral management<br> * Over 100 tables and graphs of data rates illustrating the theory, plus MATLAB program listings
Written by the pioneers of Flash-OFDM, arguably the first commercially developed OFDMA-based mobile broadband system in the world, this book teaches OFDMA from first principles, enabling readers to understand mobile broadband as a whole. The book examines the key requirements for data-centric mobile; how OFDMA fits well with data networks; why mobile broadband needs to be IP-based; and how to bridge communications theory to real-world air interface design and make a good system choice between performance and complexity. It also explores the future of wireless technologies beyond conventional cellular architecture. One of the key challenges faced by newcomers to this field is how to apply the wireless communications theory and principles to the real world and how to understand sophisticated commercial systems such as LTE. The authors use their firsthand experience to help graduate students, researchers and professionals working on 4G to bridge the gap between theory and practice.
